As modern electronics evolve, they continue to shrink in size, yet increase in power density, and in the amount of heat they generate during operation. In order for these electronic devices to perform properly, their temperature must be strictly controlled within a given temperature range. Often, designers will attach heat sinks to the electronic devices to dissipate this excess heat. Typically heat sinks include fins or pins to increase the surface area of the heat sink within a constrained space and thus correspondingly increase the heat transfer capacity of the heat sink.
